Design Communications II

Spring 2005


The Following are my contributions to the RC Flying Wing Project. My portion of the project is to design the camera mount which

will hold a camera with the purpose of taking aerial photos while the plane is in flight.


Here is the RC Flying Wing Concept E-mail that I used as preliminary overall specifications for the design of the angled camera mount.


Here is the RC Flying Wing Webpage I made for the project.


Here is the camera mount webpage I made.


Here is the first concept sketch for the camera mount that I came up with for the RC Flying Wing.


The model files for all parts mentioned below are located in the file located at V:\MEC\1012\Spring_05\Projects\RCFlyingWing\cameramount.


This is the mounting box for the camera mount.  (Model filename is “cameramountbox.ipt”)

I took Shawn Clement’s existing landing gear mounting box model and ultimately redesigned it to the point where I might as well have started from scratch.


I created a “universal” female hinge for the angle mount of the camera mount.  (Model filename is “femalehindge.ipt”)


I created a mounting platform for the angle mount.  (Model filename is “adjustableplatform.ipt”)


I updated my progress status on the project communication layout chart.


After talking with Jeremy Singley, I thought of a better design for the camera mount so that the angle mount is now redesigned to add greater precision in angling the camera slope, as well as greater dampening of vibrations due to the engine of the plane.


I further revised the design after talking with Shawn Clement and created a concept sketch of the angle mount


This is the modified mounting box for the camera mount. (Model filename is “cameramountbox.ipt”)


I created a turnbuckle assembly consisting of two eyehook screws and a nut with right hand threading

at one end and left hand threading at the other.  (The right hand and left hand eyehook screw model filenames are

“righthandhook.ipt” and “lefthandhook.ipt” respectively.  The turnbuckle nut model filename is “turnbucklenut.ipt”)


I assembled the camera mount and constrained it into a fully functioning assembly. (See movie) 

To do this I created algebraic functions that forced the turnbuckle nut to advance 1/20th of an inch on both

screws for every degree it turns.  The assembly model is named “assembly1.iam”


I sent Shawn Clement an e-mail on 2/28/05 requesting size specifications for the camera to be held by the mount.


After Shawn gave me the camera specifications I asked for, I drew up a rough dummy model of the camera. 

The model filename is “cameradummy.ipt”.


I used the dimensions of the dummy to create a sheet metal encasement for the camera to fit into. 

(The hole on the bottom is for a screw and wing nut that will be used to secure the camera into the mounting assembly. 

The small rectangular box and cutout at the top of the encasement is for the mounting of the shutter servo.)

The model filename is “sheetmetalform.ipt”.


I mounted the sheet metal form and camera into the camera mount assembly and ran into size problems. 

The camera lens interfered with the turnbuckles and the camera was too high for the mounting box.


As a result, I had to scrap the part configuration I had been working on, and came up with another assembly idea that will use

            the existing parts I have created and the same basic concept as before.  The only major changes are going to be to the

assembly and the design of the female hinge.

I redesigned the universal hinge in order to fix the interference conflict the camera lens was having with the turnbuckles.

            The model filename is “newfemalehinge.ipt”


I researched types and prices of servos that could be used for snapping pictures in flight, raising and lowering the landing gear

and any other application that requires remote control of motion within the aircraft.  A large variety of servos is needed

as the one that will snap pictures within flight would not need nearly the amount of torque required to lift landing gear or

operate rudders, elevators, ailerons, or throttle. -


I found an engine that would better suit our purposes.  The new engine is lighter, more powerful, and can handle a 3 bladed propeller

which will give better take off performance, allow shorter takeoff and better climb out, and has a smaller diameter to allow for

shorter gear. – found at tower hobbies -


I started to work on ideas for the six direction paintball launcher.


I found out from Mrs. Waldo on 4/7/05 that the rapid prototype machine creates things out of layers of ABS plastic.





This following statements and links are related to my Hydroelectric Generator Project


I started the website for the Hydroelectric Generator Project.


I e-mailed Shawn Clement to recruit him to work on the hydro project on the side.


I e-mailed Jeremy Singley to see if he would be willing to design the turbine fan for the generator.
